Back what is coming next.

Sanctum is free. It always will be.

Built by one person. No investors. No subscriptions. No data sold to keep it running.

The app you downloaded is free with no time limit and no features locked away. That is not changing. And there will never be ads in Sanctum — not now, not later, not even if it grows. That is a promise, not a roadmap item.

But there is more being built. Sanctum Mobile is coming — a companion app for iOS and Android that connects to your desktop vault over your local network. No cloud. No relay. No server in between. Just your phone talking to your machine.

A one-time contribution goes directly toward building that — and toward everything else on the roadmap.

There is no pressure and no guilt if you choose not to. Sanctum works exactly the same either way.

Contributions are voluntary. Not a charity donation. Not tax deductible. No goods or services provided in exchange — just the satisfaction of knowing something useful keeps getting built.

Thank you for using Sanctum. — Leon Man
